THEROUX SEAM FOR S EWED ARTICLES Filed Aug. 18, 1926Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE CHARLES TI-IEROUX, 0FBRUSSELS, BELGIUM, ASSIG-NOR TO UNION SPECIAL MACHINE COMPANY, OFCHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SEAM FOR SEWED ARTICLESApplication filed August 18, 1926, Serial No. 129,963, and in' GermanyApril 19, 1926.

The invention relates to new and useful improvements in seams for sewedarticles, and more particularly to a seam for joining fabric sections.

An object of the invention is to provide a seam for joining two sectionsof fabric which is formed by two threads, one above and the other belowthe fabrics, and wherein the thread above the fabrics extends in asingle line along the edge of the fabric, and at intervals extends in adouble line, and wherein said thread is formed into a series of loopspenetrating the fabric, all of said loops on the under face of thefabric being brought to the line of the needle thread parallel with theedge of the fabric and secured by looper thread loops so that in thefinished seam, there is, in effect, a straight line of interlocked chainstitches parallel with the edge of the fabric, and at intervals, adouble line of thread leading along the upper face of the fabric at anangle to the line of stitches, then down through the fabric and back tothe line of stitches.

A further object of the invention is to provide a seam of the abovecharacter wherein the fabrics'are so overlapped that the straight lineof stitches will pass through only one of the fabrics, while the threadslaid at an angle thereto extend through an overlapping layer of fabricand serve as the sole means for securing the fabrics together.

A still further object of the invention is to provide a seam of theabove type wherein the fabric entered by the straight line of stitchesis folded back upon itself so as to enclose a cord or reed, and thestitches serve to secure the folded portions of the fabric together.

In the drawings which show by way of illustration one embodiment of theinvention- Figure 1 is a plan view of the seam embodying theimprovements;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1; I

Fig. 3 is a bottom plan view of the seam on a very much enlarged scale,and

Fig. 4 is a perspective View of the upper thread with the loops formedtherein on a very much enlarged scale.

The invention is directed broadly to a seam for sewed articles, and moreparticular ly to a seam for joining two fabric sections which overlapeach other. In the preferred form of the invention, a cord such as areed is placed in the folded section of'fabric, and the folded sectionof the fabric overlapped by another section of fabric such as a hatsweat. The folded section of the fabric is the covering for the reed.The hat sweat and the reed coveringare secured together by threads, oneof which is preferably a needle thread and the other a looper thread.The needle thread is laid along the edge of the hat sweat in 'a singleline and at the proper intervals is formed into loops which penetratethe covering'for the reed. At spaced intervals, the needle thread islaid .at an angle to the line of stitches ust referred to, and is formedinto a loop which penetrates the hat sweat and the reed covering.Beneath the fabric sections, this loop is carried over to the lineofneedle loops first referred to. All of the needle loops are locked by alooper. thread loop which is formedinto loops passed through the needleloops and secured by succeeding needle loops in the well known manner.

Referring. more in detail to the drawings, I have shown a hat sweat 1.which is secured to a reed covering 2. This reed covering .2 is foldedback so as to enclose the reed 3. The sections of the material aresecured together by two threads, a needle thread 4 and a looper thread5*. The needle thread 4- is formed into a series'ofloops 6, 7 8 and 9 asshown in Fig. 4:. These loops pass through the reed covering only, andare disposed at the edge and in a line parallel with the edge of the hatsweat. It will be noted that; there is, in effect, a straight line ofsingle thread parallel with the edge of the hat sweat. 1. This is theneedle thread 4: extending between the needle thread loops just referredto. The needle thread 4 is laid at an angle to the edge of the hat sweatas indicated at 10 and 11. This needlethread isformed into a thread loop12 which is passed down through the fabric at the points 13, 13,respectively. The necdle thread loop 12 beneath the fabric is carriedover to a point where it is in line with the needle thread loops 6, 7and 9. The looper thread loop 5 is formed into loops 1% which are passedthrough the respective needle thread loops beneath the fabric. Thislooper thread loop 14, for example, passes through a needle thread loop6, and the loop in the looper thread is secured by the next formedneedle thread loop 7. A loop of thread 14; passes through this needlethread loop 7 and is secured by the needle thread loop 8. This is theusual manner of forming a double chain stitch.

From the above it will be apparent that a seam is provided wherein thereis, in effect, a row of double chain stitches along the edge ofoverlapped fabric sections, and these stitches penetrate only one of thefabric sections. The other fabric section is secured thereto by threadloops alone which are projected laterally from the line of stitches andpass through the section of fabric which is secured thereto. It will beunderstood, of course, that the laterally projected loops may be formedat any desired intervals rather than at every other feed interval asshown in the drawings. It will also be understood that the laterallyprojected loop may be at an acute angle to the line of stitches insteadof as at right angles thereto as shown in the drawmgs.

While I have shown the seam as applied to the securing of a reed to ahat sweat, it is understood that itmay be used for other purposes.

Having thus described the invention, what I claim as new and desire tosecure by Letters- Patent, is-

Seam for sewed articles comprising a folded fabric section enclosing acord, a sec- 0nd fabric section over-lapping said folded fabric sectionto a line adjacent the cord, and stitching threads for securing thefabric sections together, including a needle thread formed into a seriesof loops pentrating the fabric section in a line outside of, adjacentand parallel with the edge of the upper fabric section, said needlethread being carried at an angle to the edge of the fabric sections atintervals including a plurality of needle thread loop formations, andformed into a loop penetrating said second named fabric section at adistance back from the edge thereof, said last-named needle thread loopbeing carried beneath the fabric to the line of the first named needlethread loops, and looper thread loops enchained with said needle threadloops in succession and disposed in a line parallel with the edge of theedge of the fabric sections.

In testimony whereof, I affix my signature.

CHARLES TI-IEROUX.
